There's tons of Chinese MCU boards including some with wifi for that
much.  For something more local, https://www.adafruit.com/products/1500
seems pretty cool.  It may be a bit too small for a resident Forth but
seems like a good target for a tethered one (AVR cpu, 8k flash, 0.5k
ram, 0.5k eeprom).  Olimex has something like it too:

"At one time TI sold an MSP430 board for $4.30.  That's the only thing 
I've seen that was comparable in price and still useful."

Cypress has small PCBs of their PSoC4 and PSoC5 chips for $4 and $10:
CY8CKIT-049 and CY8CKIT-059 (32K flash / 4K RAM or 256K / 64K)
These are ARM processors: Cortex M0 and M3; with programmable analog and digital.

I had forgotten about those.  I have a few of them, but found the tools 
to be awkward to use.  Specifically I was asked to dig out the serial 
port code for a Mecrisp port.  Their tools try to be usable without 
knowing anything about the parts, so the underlying code is hard to get 
to.  I guess once you get up and running with a couple of projects under 
your belt their tool isn't so bad, but it was not easy to come up the 
learning curve.  Maybe my learning horsepower isn't what it used to 
be... lol

I wanted to do a project with one of these boards, but in the end used 
at TI Launchpad.
